阿里云kafka使用记录（python版本）

kafka端

 

consumer vpc版代码

 

import socket
from kafka import KafkaConsumer
from kafka.errors import KafkaError

# context.check_hostname = True

consumer = KafkaConsumer(bootstrap_servers=['192.168.xx.xx:9092'],
                        group_id='xx',
                        api_version = (0,10)
                        )

print('consumer start to consuming...')
consumer.subscribe(('xx',))
for message in consumer:
    print(message.topic)
    print(message.offset)
    print(message.key)
    print(message.value)
    print(message.partition)

 

producer vpc版代码

#!/usr/bin/env python
# encoding: utf-8

import socket
from kafka import KafkaProducer
from kafka.errors import KafkaError

producer = KafkaProducer(bootstrap_servers=['192.168.xx.xx:9092'],

                        retries=5)

partitions = producer.partitions_for('xx')
print('Topic下分区: %s' % partitions)

try:
    future = producer.send(topic='xx', value=b'hello aliyun-kafka!')
    future.get()
    print('send message succeed.')
except KafkaError as e:
    print('send message failed.')
    print(e)
